Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor panel mounting structure, particularly when a plurality of floor panels such as lightweight aerated concrete (ALC) are laid on a beam made of H-shaped steel to form a floor. The present invention relates to a floor panel mounting structure.

[0002]

2. Description of the Related Art Conventionally, lightweight cellular concrete (ALC)
When using such panels as floor panels, use a large beam composed of H-shaped steel material with high length and high strength as the main beam material of the building frame, and the floor composed of H-shaped steel material between the large beams. A beam is constructed by joining small beams that transmit a load to a large beam, and a plurality of floor panels are laid on the beam to form a floor. As a concrete mounting structure of such a floor panel, as shown in JP-A-62-174432, etc., a beam member is attached to a beam, and a beam is attached to the beam member. There is a panel floor that is constructed so that the upper end of the beam is almost the same height as the upper end of the girder, and a lightweight cellular concrete panel is placed on all the girders and girders. Further, as shown in FIG. 14, since the girder 1 has the projection 21 at the joint portion, as shown in FIG.
After mounting the girders 2 from the upper surface of the girder and installing the C-shaped steel 20 on the girders 1 to smooth the space between the girders, as shown in FIG. 16 and FIG. It is often practiced to place a lightweight cellular concrete panel 3 on the top of the floor to form a panel floor. The girder 1 shown in FIG. 16 is perpendicular to the girder 2 and the girder 4 shown in FIG.
Is parallel to the beam 2. Thus, the girder 1 and the girder 4 are both provided at the same height because both the girder 1 and the girder 4 are vertically attached to the steel column provided in the height direction of the building.

[0003]

In the conventional floor panel mounting structure, there is a distance between the lower surface of the floor panel 3 and the lower surface of the girder 1, and the ceiling is stretched under the girder 1. If the height from the surface to the ceiling is invariable, the height required for one floor in a multi-story building is inevitably high.To build a multi-story building, either increase the building height or increase the floors. I had to reduce it and build it.

In view of the above points, the present invention is to provide a floor panel mounting structure capable of lowering the height of the ceiling of the lower floor and the upper surface of the floor panel of the floor above it, and in the living space. An object of the present invention is to provide a floor panel mounting structure that can cope with a height between a certain floor and a ceiling and can reduce the height of a building when building a building of the same floor. In particular, if the height of the building can be reduced, it is effective because a building with a desired number of floors can be obtained even if there is a diagonal restriction condition in the construction method.

[0005]

The present invention provides a floor panel mounting structure in which a beam is formed by a large beam having a high height and a small beam having a low height, and a floor panel is laid on the beam. The upper end of the beam is made lower than the upper end of the girder, and the lower surface of the floor panel is laid along the upper end of the beam.

In a general building, there are large beams at least at the four corners thereof, and as a result, large beams also exist in the direction parallel to the small beams, but floor panels are placed on the side surfaces of the large beams that are parallel to the small beams. A member can be attached and the floor panel can be laid by mounting the lower surface of the floor panel on the upper part of the floor panel mounting member and the upper part of the adjacent beam. The distance between the upper surface of the girder and the upper surface of the girder is preferably such that the upper surface of the girder is about half the thickness of the floor panel. This is because the top surface of the floor panel is about half the thickness of the floor panel above the top of the girder, and the joint bars are inserted between the floor panels to fix the floor panels with mortar and move the floor panels. This is to prevent it from happening. Further, if the lower surface of the beam is lower than the lower surface of the girder, the distance between the lower surface of the floor panel and the lower surface of the beam becomes large, which is not preferable.

[0007]

According to the present invention, the distance between the ceiling of the lower floor and the upper surface of the floor panel can be shortened, and the living space can be increased and the height of the building can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a view showing an embodiment of the present invention and is a perspective view showing a floor panel mounting structure by showing only two floor panels. In the figure, 1 is a large beam, 2 is a small beam, 3 is a floor panel, and 6 is a small beam mounting bracket. The girder 1 has a larger distance in the height direction than the girder 2, and the girder 2 is connected to a vertical surface of the girder 1 at a predetermined position by an L-shaped girder mounting bracket 6. As shown in the figure, the upper end of the girder 2 is attached so as to be lower than the upper end of the girder 1, and the lower end of the girder 2 is attached so as not to be lower than the lower end of the girder 1, For example, in the figure, the lower end of the girder 2 and the lower end of the girder 1 have substantially the same height. In this way, the girder is composed of the girder and the girder, and the floor panel 3 is placed on the girder 2.
It is laid between the crossbeams 2 in the longitudinal direction. No floor panel is laid on the upper surface of the girder 1. In this way, the height of the floor panel mounting structure is only the total height of the floor panel and the beam, so that the distance between the ceiling of the lower floor and the floor panel upper surface can be shortened.

After the floor panel is laid on the beam as described above, mortar is placed in the joints of the floor panel to prevent the floor panel from moving. FIG. 2 is a cross-sectional view showing such a structure. A girder 2 is vertically attached to a girder 1 by a girder mounting bracket 6, and a floor panel 3 is laid on an upper surface of the girder 2. The mortar 12 is placed through the joint rebars 11 between the three. Mortar 12 is also cast on the upper surface of the girder 1.

When a floor panel is laid between the beam 2 and the parallel beam 4, the floor panel mounting member 5 is attached to the side surface of the beam 4, for example, as shown in FIGS. 3, 4 and 5. The floor panel is laid between the upper portion of the floor panel mounting member 5 and the upper surface of the adjacent beam in the longitudinal direction. The floor panel mounting member 5 may be an L-shaped steel material 5a as shown in FIG.
The C-shaped steel material 5b may be used as shown in FIG. 5 or the flat plate 5c may be used as shown in FIG. To attach the L-shaped steel material 5a or the C-shaped steel material 5b to the girder 4, a plate-shaped mounting member 7 is fixed to the girder 4 by means such as welding, and the floor panel mounting member 5 is welded to the mounting member 7. It may be fixed by tightening or bolts. To attach the flat plate 5c to the girder 4,
The rib-shaped mounting member 8 is fixed by welding or the like, and the flat plate 5c
May be fixed to the mounting member 8 by welding or the like.

As described above, the mortar is placed on the joints of the beam 2 and the beam 4 according to the upper surface of the floor panel.
If there is a gap between the upper end side surface of the girder 4 and the side surface of the floor panel, it may leak downward. In order to prevent this, it is desirable to install a member for mortar leakage so that the mortar does not leak downward. The mortar leakage prevention member may be an indeterminate material such as rock wool, but a plate-shaped mortar stopper member may be fixed and used by means such as welding.

FIGS. 6, 7, and 8 are cross-sectional views of the case in which the mortar leakage prevention member is fixed to FIGS. 3, 4, and 5, respectively, showing the case where the small beam and the large beam are parallel to each other. FIG. 6 is a sectional view in which a mortar leakage prevention member 9a is fixed between the L-shaped steel material 5a and the upper end of the girder 4, and FIG. 7 is a mortar leakage prevention member between the C-shaped steel material 5b and the upper end of the girder 4. Member 9b
7 is a sectional view in which the mortar leakage prevention member 9c is fixed between the flat plate 5c and the upper end of the girder 4.

FIGS. 9 and 10 are cross-sectional views of the case where the mortar leakage prevention member is fixed to FIGS. 1 and 2, respectively, showing the case where the small beam and the large beam are orthogonal to each other. FIG. 9 is a cross-sectional view in which an L-shaped steel material 10a as a mortar leakage prevention member is continuously fixed between the beam 2 and the upper end of the girder 1, and FIG. 10 shows a Z-shaped steel material 10b as a mortar leakage prevention member. It is sectional drawing which fixed continuously.

In order to make the height of the joint rebar 11 passing between the adjacent floor panels 3 as shown in FIG. 2 constant, as shown in FIG. 11, the beam 2 and the beam 4 parallel to the beam 2 are used. The fixed metal piece 13 may be attached on the top of the fixed metal piece 13, and a hole through which the joint rebar 11 penetrates may be provided in the fixed metal piece 13 so as to maintain the height of the reinforcing bar. An enlarged view of the fixed hardware 13 provided on the beam 2 is shown in FIG. Further, as shown in FIG. 11, it is preferable that the joint rebar 11 is continuous from end to end for reasons such as earthquake resistance, and when the joint rebar 11 is replenished, for example, as shown in FIG. Nut 14
Welded and fixed, and threaded to the end of the joint rebar 11, screw the joint rebar 11 into the nut 14 to connect with each other,
As shown in FIG. 11, a long nut 15 may be arranged in the middle to connect the joint reinforcing bars 11 to each other.

[0015]

According to the present invention, the distance between the ceiling on the lower floor and the upper surface of the floor panel on the floor above can be shortened, and the space between the floor and the ceiling, which is a living space, can be increased. it can.
Further, when constructing buildings on the same floor, the building height can be lowered. In particular, if the height of the building can be reduced, it is possible to obtain a building with a desired number of floors even if there is a condition that the building is restricted by diagonal lines.

Further, in the case of a steel frame body in which a girder parallel to the girder exists, if the floor panel mounting member is attached to the side surface of the girder parallel to the girder, the same effect as described above can be achieved.
